Abstract
Precise, adherent deposits of a metal such as palladium are formed on an substrate such as polyimide, silicon dioxide, tantalum oxide and polyethylene terephthalate by contacting the substrate surface with a solution of the metal, and then exposing the surface through the solution to laser radiation characterized by a wavelength absorbable by the substrate and a power density and fluence effective to release electrons to promote deposition of the metal onto the substrate without thermal activation of the substrate or the solution.
